Slope staking

For both stakeout point and stakeout lines, side slope and catch point stakeout modes are available that enable staking out the slope or the catch point between this slope and the existing ground. This function can be applied to any earthwork operation that involves a tie to the current ground surface. Examples include staking earthworks for pad placement, earth dams, site drainage, ponds, lagoons, embankments, and keyways.

The tie-slope can be projected from a 3D point using an entered bearing or from a 3D Line. After defining either one of those, the stakeout process is very much alike. Tap the Stake mode icon on the bottom of the status panel on the right side of the main panel:

	Stake catch point
	Stake side slope
	Stake line

You can then select line, side slope or catch point. Use the Define Side Slope screen to select the direction of the slope and whether you define a cut and/or fill side slope to the left or right of the reference line for a line, or a bearing for staking from a point. To select what the slope designation is to be based on, alter the selection in the Slope direction field.

The software computes the elevation of the reference line at that point and projects the designated cut and/or fill side slope magnitudes from that reference point, through your position, along a line referred to as the slope indicator. The slope indicator line is shown in the map view, extending from the reference line to the currently predicted catch point location. In predicting the location of the catch point, if you have defined both cut and fill slope magnitudes, the software determines whether the cut slope or fill slope is applicable at the reference point.

When staking building pad side slopes, the building pad has both internal and external right-angled corners. If you are staking external corner points, then the software automatically calculates the side slope as projected radially from the corner point. At an internal corner, the software calculates the catch point at a bi-sectional angle.

The Catch point option enables you to stake out points where the side slope intersects the ground surface as it is found to exist. As you stake catch points at fixed intervals, you should adapt to the existing terrain and be aware of the effect that it may have on the location of the daylight line. You can freely switch between the Stake at fixed intervals mode and Stake at randomly chosen interval modes.

The Line option enables you to stake out the side slope’s reference line. The software guides you to the line at the nearest point to where you currently are, or to a specific station.

The Side Slope option enables you to place a grade stake at any required location on the side slope between the reference line and the catch point. You can toggle between the different stakeout methods by selecting the icon at the bottom of the status bar on the right side of the main panel.
